CLOTH-SUBFACING DEVICE.

Application filed July 2,

To all whom it may concern:

Be it known thatI, VILLIAM E. Ross, a citizen of the United States,residing at Chi-' cago, in the county of Cook and State of Illinois,have invented certain new and use ful Improvements in Cloth-SurfacingDcvices, of which the following is a specification.

The present invention relates to devices for surfacing materials, suchas cloth, and has particular reference to the raising of a nap upon thesurface of the cloth.

Among the objects of the invention are to provide an improved method anddevice for rasing a nap upon the surface of cloth or the like; toprovide the device with angularly projected burred bristles or bristleswith burrs at the free ends thereof capable of entering into the cloth asubstantial distance and then leaving the cloth while raisi'ng a nap soas to leave a raised or lifted nap on the surface thereof; to provide ade vice so that the bristles will have a rolling and dragging action ofa cl'un-acter which will cause the entry of the burrs into the cloth asa. relative motion is effected between the cloth and the bristles, thebristles having such resiliency that as they are caused to leave thecloth, the burrs will raise a nap and readily disengage themselves fromsaid nap; to provide for adjustably varying the resistance to the rotaryaction of the bristles, preferably by an adjustable resilient frictionalbrake or the like whereby the drag on the bristles during peripheralmovement of the bristles in a direction opposite to the direction ofprojection of the burrs will cause the barred ends of. the bristles toenter the cloth and also to travel along the cloth; to provide a devicecombining the features of nap raising burrs capable of entering thecloth, ressure for ausing such entry, and a frictlonal drag which, withthe pressure applied and the 'relative movement of the cloth and thedevice, will effect the desired raising of the nap on the surface of thecloth; and to rovide such other and further objects, a vantages andcapabilities as will later more fully appear and are inherentlypossessed by the invention.

Referring to the drawings, F ig. 1 is a side view of a deviceconstructed in accordance with the inventionrFig. 2 is a yiew partiallyinsection' on the line 2-2 of Fig. 1; Fig. 3 is a fragmentary detailedview in sec= tion of part 'of the device; Fig. 4 is a which is rotatablymounted or journaled a roller 5 carrying upon its periphery an annularset of bristles 6, aselearly shown in Figs. 1 and 2 of the drawing;l

The roller 5 is rotatably ounted upon a shaft or pin 7 having means atone end for connection to the arm 4 and being threaded at the other endto receive a thumb nut 8 having a hub portion 9 bearing against an endof a helical spring 10 hearing at its other end against a friction ordrag plate or disk ll fastened to one side of the roller 5. At the otherend of the shaft 7, in the form shown in 'Fig. 2 of the drawing, isformed a head 12 having a flange 13, the latter being cut sccantally toform a shoulder 14 abutting against a corresponding shoulder 15 formedin the arm 4. The cooperation of these shoulders prevents the turning ofthe shaft about its axis. The arm 4 has an opening or aperature withinwhich the enlargement l2 fits, as clearly shown in Fig. 2 of thedrawing. The enlargement 12 has a shoulder portion 16 having frictionalengagement with a frictional or drag plate or disk 17 secured to theother side of the roller from that to which the plate 11 is secured.

In the form of device shown in Fig. 5, the mode of connection betweenthe shaft 7 and the arm 4 is b way of a cross pin 18 extending througlthe apertured end of the arm 4 and the end of the shaft passingthercthrough. In this waythe pin 18 prevents a relative rotation of theshaft 7 with respect to the arm 4. The end of the arm 4 is provided witha frictional surface 19 hearing against the outer face of a flatfrictional or drag disk 20 secured to a side of the roller, andcorrespondin to the plate 17 in the form shown in l ig. 2 of the drawinThe ristles are connected, preferably, in groups, and in circular seriesabout the periphery of the roller, to form a substantially uniformoperating surface, their inner ends'being fastened into the roller andtheir outer ends extending outwardly but not radially, althoufh curvedin a general direction more or ess tangentially about the roller. Theouter or free ends of the bristles are suitably formed, as by grindingwhile under pressure, upon an emery wheel or like or similar abrasivedevice, with angularly projected burrs 21 extending in the same generaldirection as clearly shown in Figs. 3 and 4 of the drawing. The bristlesare preferably of metal and resilient, such as steel wire, and are sotreated that they are not corr'odible. As shown in Fig. 3 of thedrawing, the bristles are curved or inclined toward the direction inwhich the device is to be moved or drawn over the surfam of cloth ormaterial to be treated.

It is to be understood that while a handoperated device is chosen toillustrate the invention, the invention also comprehends the idea ofsupporting the bristles in any manner desired so long as there isrelative movement between the cloth or material to be treated and thebristles, in the direction above indicated, irrespective of whether ornot the cloth be moved and the bristles held for rotation about astationary axis or the bristle carrying device be moved as a wholerelative to the cloth, the latter being in stationary relation.

In operation the device is used so as to cause a rolling of the roller 5together with the bristles carried thereby over the surface of clothsuch as the cloth piece 22 shown in Fig. 3 of the drawing. In order thatthe same will not ride idly over the cloth without producing the desiredeffect, a drag or frictional resistance is applied to the roll 5 by asuitable turning of the thumb nut 8 so as to compress the spring 10 tothe extent of obtaining: the desired frictional engagement between anend of the spring and the friction disk 11 as well as the shoulder 16and the friction disk 1?. Viiih the proper amount of frictional drag,should the device be drawn over the cloth in a direction correspondingto the direction of projection of the burrs 21, the roller and thebristles carried thereby will be rotated, thereby causing the burrs topenetrate the material a substantial distance. The bristles will bebent. or flexed somewhat as the burrerl ends thereof enter the cloth.and as the rolling continues, and the trailing, bristles which arelifted from the cloth will resiliently act in such a direction as tocause the burrs 21 to lift a nap out of the cloth so as to leave uponthe cloth a nap 23 as shown in Fig. 3 of the drawing, the burrs leavingthe cloth at such an angle as to readily disengage themeclvvs from thenap. This effect results from the travel of the device, together withthe fric tional drag upon the roll, which cause the roll to rotate aswell as to force the burred ends 21 to yieldably enter the cloth,result- 'ing in a reflex action of the bristles as the leave the clothso as to cause the burrs to lift the nap.

While I have herein described and upon the drawings shown a preferredand modified embodiment illustrating the invention, it is to beunderstood that the invention is not limited to the particularconstruction details and arrangement of parts shown an described, butthat other constructions, details and arrangements of parts are comprehcnded by the invention without departing from the spirit thereof.
